<<On the heels of Democratic adventures like JFK using the FBI and the IRS to investigate and harass his opponents (Nixon and others).
<<How far back you want to take it?>>
I believe the original standard here relating to Hillary's unfitness for the bench was the destruction or disappearance of evidence. That being the case, I'd take it as far back as it CAN be taken, which is where I left it, with the destruction of the Nixon tapes by his secretary, Rosemary Woods. However if you want to start a new contest based on Presidential misuse of the FBI and IRS, I'll take your JFK and raise you one Nixon and his Dirty Tricks Department including use of the FBI to infiltrate anti-war protest groups, provoke them to violence and generate intra-group conflicts, including the FBI attempts to blackmail Martin Luther King into committing suicide.
